Abstract:
A vehicle with at least two wheel axles comprises a folding frame having an "inverted V" shape on a longitudinal-vertical plane (X-Z) comprising a first rear arm (11) and a second front arm (12) merged in a upper intersection portion (13), the end (12a) of the second arm (12) being coupled to a front steering tube (14) with a substantially vertical axis or with a slight tilt toward the intersection portion (13) of the "inverted V" and tilted with respect to the second arm (12) so as to define an angle with it on the longitudinal-vertical plane (X-Z), wherein a transverse axis joint (17) is placed at the intersection portion (13) of the two arms (11,12), wherein the first (11) or the second arm (12) has an extension beyond the intersection portion (13) defined by a section (1 1 c) of the arm whose free end is coupled to a saddle (110) of the vehicle and wherein the first arm (11) is intended to support and discharge to the ground at least part of a vertical load weighing on the saddle (110).
Abstract:
An optical device (1) for indicating the glide angle of aircraft comprises at least one light source (2) of predetermined colour, at least one unit (4) for creating a light image, coinciding with the light source (2), and at least one unit (5) for projecting the light image at a distance. The light source (2) comprises an electroluminescent light panel (3).
Abstract:
A guide apparatus for supports (20) for sensors (30) able to move by translation in fixed guides (10) integral with the sail (Ia) of submarines (1) and the like upon activation of an actuator (40), where the fixed guide (10) has a polygonal cross-section, at each vertex (10b) of the guide (10) there being at least one structure with the shape of a prism (11) extending in the vertical direction (Z - Z) along the entire body of the guide, the prismatic elements (11) extending towards the inside of the guide (10) in such a way as to form at least two sliding surfaces (12) for corresponding sliding blocks (22) belonging to the tube (20) to be moved by translation.
Abstract:
The stabilising device for boats comprises two propulsion units (2) emerging from a hull of the boat and positioned on opposite sides of a boat longitudinal axis (A3), each of the propulsion units (2) comprising a fin (3) and motor means for rotating the fin (3) both about its first axis (Al) of longitudinal extension, and about a second axis (A2).
